Examples of com.netflix.server.context.DirectionAwareContextSerializer

com.netflix.server.context.DirectionAwareContextSerializer

A replacement for {@link ContextSerializer} for {@link BiDirectional} contexts that requires information about thedirection of flow (i.e. request or response). For legacy reasons, this class extends {@link ContextSerializer}, the easier way to implement a direction aware serializer will be to extend {@link DirectionAwareSerializerAdapter} whichprovides a default implementation of the methods in {@link ContextSerializer}

Directions

Directions carry different meanings when associated with serialization type. Infact its usually the opposite for serialization and de-serialization. Following is the definition:

{@link Direction#Inbound}

Serialization: Serializing for adding to the response. De-serialization: De-serializing for reading the request.

{@link Direction#Outbound}

Serialization: Serializing for adding to the request. De-serialization: De-serializing for reading the response. @author Nitesh Kant
